JP2 and JP3 are both short: Pin15 is short with pin2 and pin16 is short with pin1. Backlight powered up via V DD (pin2) and V SS (pin1). Customer does not need to supply power to pin15 and pin16. This is the Standard setting. 2. JP2 short and JP3 open: Pin 15 is short with Pin2 and pin16 is NOT short with pin1. Backlight is powered with V DD (same as logic circuit) and customer should keep pin 15 floating or connected to V DD. Customer could control the backlight independently ON or OFF with pin16 L or H. 3. JP2 open and JP3 short: Pin 15 is NOT short with pin 2 and pin16 is short with pin1. Backlight is common VSS with logic and customer should keep pin16 floating or connected to GND (V SS ). Customer could control the backlight ON or OFF with pin15 H or L 4. JP2 and JP3 are both open: The backlight is fully independent with the logic, control the backlight via pin15/pin16 or A/K. Keep the current consumption for LED backlight follow the spec. 5. J1 short: Bezel and screw holes connected to GND. J1 open: Bezel and screw holes floating 6. Never change the J2 and J3, it may burn off your system. Note: J1, JP2 and JP3 are #0805 0 ohm resistors on the rear side of the PCB. 9

Return cursor to the original status. namely, bring the cursor to the left edge on first line of the display. Make entry mode increment (I/D = 1 ). Return Home RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 0 0 0 0 0 0 0 1 * Return Home is cursor return home instruction. Set DD address to "00H" into the address counter. Return cursor to its original site and return display to its original status, if shifted. Content of DD is not changed. Entry Mode Set RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 0 0 0 0 0 0 1 I/D SH Set the moving direction of cursor and display. I/D: Increment / decrement of DD address (cursor or blink) When I/D = "High", cursor / blink moves to right and DD address is increased by 1. When I/D = "Low", cursor / blink moves to left and DD address is decreased by 1. * operates the same as DD, when read from or write to. SH: Shift of entire display When DD read ( read/write) operation or SH = "Low", shift of entire display is not performed. If SH = "High" and DD write operation, shift of entire display is performed according to I/D value (I/D = "1", shift left, I/D = "0" : shift right). 16

D: Display ON/OFF control bit When D = "High", entire display is turned on. When D = "Low", display is turned off, but display data is remained in DD. C: Cursor ON/OFF control bit When C = "High", cursor is turned on. When C = "Low", cursor is disappeared in current display, but I/D register remains its data. B: Cursor Blink ON/OFF control bit When B = "High", cursor blink is on, that performs alternate between all the high data and display character at the cursor position. When B = "Low", blink is off. Cursor or Display Shift RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 0 0 0 0 1 S/C R/L * * Without writing or reading of display data, shift right / left cursor position or display. This instruction is used to correct or search display data. (Refer to Table 4) During 2 line mode display, cursor moves to the 2nd line after 40th digit of 1st line. Note that display shift is performed simultaneously in all the line. When displayed data is shifted repeatedly, each line shifted individually. When display shift is performed, the contents of address counter are not changed. S/C R/L Operation 0 0 Shift cursor to the left, is decreased by 1. 0 1 Shift cursor to the right, is increased by 1. 1 0 1 1 Shift all of the display to the left, cursor moves according to the display.

When DL = Low, it means 4 bit bus mode with MPU. So to speak, DL is a signal to select 8-bit or 4 bit bus mode. When 4 bit bus mode, it needs to transfer 4 bit data by two times. N: Display line number control bit When N = Low, it means 1 line display mode. When N = High, 2 line display mode is set. F: Display font type control bit When F = Low, it means 5 X 8 dots format display mode When F = High, 5 x11 dots format display mode. Set Address RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 0 0 1 5 4 3 2 1 0 Set address to. This instruction makes data available from MPU. Set DD Address RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 0 1 6 5 4 3 2 1 0 Set DD address to. This instruction makes DD data available from MPU. When 1 line display mode (N = 0), DD address is from "00H" to "4FH". In 2 line display mode (N = 1), DD address in the 1st line is from "00H" to "27H", and DD address in the 2nd line is from "40H" to "67H". 18
A August. 05, 11 19 / 29 Read Busy Flag and Address RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 1 BF 6 5 4 3 2 1 0 This instruction shows whether ST 7066 is in internal operation or not. If the resultant BF is High, it means the internal operation is in progress and you have to wait until BF to be Low, and then the next instruction can be performed. In this instruction you can read also the value of address counter. Write Data to RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 1 0 D7 D6 D5 D4 D3 D2 D1 D0 Write binary 8 bit data to DD /. The selection of from DD,, is set by the previous address set instruction : DD address set, address set. set instruction can also determine the direction to. After write operation, the address is automatically increased / decreased by 1, according to the entry mode. Read Data to RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 1 0 D7 D6 D5 D4 D3 D2 D1 D0 Read binary 8 bit data from DD /. The selection of is set by the previous address set instruction. If address set instruction of is not performed before this instruction, the data that read first is invalid, because the direction of is not determined. If you read data several times without address set instruction before read operation, you can get correct data from the second, but the first data would be incorrect, because there is no time margin to transfer data. In case of DD read operation, cursor shift instruction plays the same role as DD address set instruction : it also transfers data to output data register. After read operation address counter is automatically increased / decreased by 1 according to the entry mode. After read operation, display shift may not be executed correctly. NOTE: In case of write operation, after this is increased / decreased by 1 like read operation. In this time, indicates the next address position, but you can read only the previous data by read instruction. 19

A August. 05, 11 25 / 29 HANDLING PRECAUTIONS (1) Treat polarizer very carefully since it is easy to be damaged. (2) When cleaning the display surface, use soft cloth (e.g. gauss) with a solvent (recommended below) and wipe lightly. ethyl alcohol iso prcolol Do not wipe the display surface with dry or hard materials that will damage the polarizer surface. Do not use the following solvents: water ketone aromatics (3) Direct current causes electro-chemical reaction with remarkable degradation of the display quality. Give careful consideration to prevent direct current at ON/OFF timing and during operation. (4) Avoid strong shock and drop from the height. (5) To prevent LCD panels from degradation, do not operate or store them exposed directly to sunshine or high temperature / humidity.
